In this seemingly random episode, Andrew, Laura and Ben hear from a herd of scientists on dinosaur discovery, Chaos Theory and de-extinction, and try to avoid talking about Jurassic World for as long as possible.

Phil Manning chats to us about robot dinosaurs, finding fossils on beaches, and studying them using x-rays; Jim Al-Khalili gives us a quick run-down on chaos theory; Kathryn Boast lets us listen to some cosmic rays; and Beth Shapiro explains some of the science behind her book How to Clone a Mammoth.
